would you build it with the panel in front of the sub square or round (magnet in sealed section)? its going to be an experiment obviously but i would appreciate everyones advice and ideas before i waste my time and wood.

realy tough choice about that panel in from of the sub. i would try it first with a round cutout, then with a square cutout. i remember someone asked in the past about using kickers, but never got an answer

trying the round and then the square means time and work? why would you try round?

Is this a trick question?You wanna fit a square sub in a round hole? and put a DB12 on steroids? My My My.....

I answered that old thread in full detail with intense thought and research. I was on the phone with Kicker as well as multiple E mails. When one of the technical heads of R & D met with me at my lab we went over the transmotional properties as well as the dampended factor that gives the DB its amazing ability to handle excessive wattage.We decided to silicon gummy bears to the wall of the DB and reinforce the sides with popsicle sticks.The results were amazingly sweet when the voice coil heated up.

I am sorry to say that because of the objectional photos of melted gummy bears that was posted, I was forced to remove all of my post.

Cruelity to Gummy bears is considered abusive and I may be facing a law suit with the unnamed candy maker Daree.

Why? Because it is in the design and you should never experiment with Steve D 's Designs what-so-ever.

But for real, the only reason the circle hole is in the DB12is to make it behave like the original DB10. The flow of the air is what makes the box perform so well. So keep the hole, keep the flow, Keep the Amazment.

I agree with J rock now that I am all serious.its not about surface area but air flow.

If you change the hole it changes the flow. The DB is not just a simple box, if you think that, read the papers on the DB10

The baffle design is unique.

I am messing with a DB 12 sealed chamber at the moment. I am attempting to reduce resonant peaks by baffles, foam and maybe stuffing.. Everything is to spec but the sealed chamber is up for play.I am not in a hurry to finish it because I can't do any measuring of the changes as of yet.. still need a mic and some cords to finish my Speaker testing PC..Other project are taking all my time at the moment also. the DB has been sitting for three weeks now. It should be interesting if ever get around to it. there is a limit to the play area because of the movement of the baffle. Anyway if i do decide to experiment as time comes availiable I will start thead on it.
